O-ring, End Cap
Part No: V 04-2390-52-700
Pack of 4
V 04-2390-52-700: O-ring, End Cap – A specialized static elastomer sealing ring engineered to fit directly underneath the air valve enclosure cap. It creates a robust pressure boundary to ensure that supply compressed air cannot leak past the terminal interface.

Key Features
- Custom-molded static cross-section geometry creates an airtight fit along high-pressure endcap boundaries.
- Keeps main pilot air pressures securely contained to prevent cycling efficiency drops or timing lags.
- Resists structural flattening, pinching, and permanent deformation under continuous bolt torque limits.
- Outstanding compression recovery lets the ring snap back instantly during rapid pressure fluctuations.
- Drops easily into standard internal tracks to speed up general tool-free preventive maintenance checks.
